GEORGE A. CROSMAN, OF SEATTLE, WASHINGTON Application filed February 26, i929. Serial No. 342,725.

This invention relates to devices for hanging and operating doors and, more especially, those of large size such as employed in automobile garages, warehouses, machine shops and the like.

llhe object of the invention, generally, is to provide devices of this character which will be of inexpensive and durable construction, and eflicient in operation.

A more specific object is to provide door suspending means adapted to cooperate with the door hinges to support heavy doors so that they cannot sag, and permitting the same to bereadily swung 'in their opening and closing movements.

A further object is to provide conveniently actuated means remote from the door to effect movement thereto by utilizing the door supporting devices as parts of the door operating appliances.

Other specific objects and advantages of the invention will appear in. the following description.

The invention consists in the novel construction, adaptation and combination of parts hereinafter described and claimed.

In the accompanying drawings,

Figure 1 is a front, elevational view of a room wall provided with a doorway, a side wall of the room in transverse section, and a pair of hinged doors equipped with an embodiment of my invention: Fig. 2 is a horizontal sectional view of Fig. 1; Fig. 3 is a fragmentary front elevation, partly in section through 33 of Fig. 4, illustrating to an enlarged scale the applicationof the door braces, hangers, and carriage'mounting as utilized with a sidewall track; Fig. 4 is a view partly in horizontal section and partly in plan of parts shown in Fig. 3; Fig. 5 is a view in front elevation of the door operating means; and Fig. 6 is a perspective view of a carriage track and bracket assembly.

In Figs. 1 and 2, to which reference is now had, 10 and 11 represent a pair of doors for a doorway 12 in a front wall 13 of a building and adjacent to a side wall 14 thereof.

As shown, these doors are connected to the wall 13 at opposite sides respectively of the doorway by means of hinges 15 so as to be inafter designated as the tie-rod, is disposed ,7 horizontally, or nearly so, and has one of its ends pivotally connected by a pin 181 for vertical adjustment to a coupling 182 which, in turn, is connected for horizontal swinging movement, by means of a pin 20, to Ian at tachment 21 secured to the free side of the door. The other end of a tie-rod is pivotally connected for vertical adjustment by means of a pin 18 3 to a winged connector 22 which,

in turn, is connected for horizontal swinging movement by means of a pin 221 (Fig. 4;)

to a block 23. The other above mentioned rod 19, hereinafter termed the suspensionrod, is pivotallyconnected by means of a pin 191 for vertical adjustment to said connector 22 and is thus horizontally in unison with the tie rod 18 for operating the door. The suspension rod 19 extends downwardly in angular relation with respect to the tie rod 18 and has its lower end pivotally connected for verticalv adjustment to a coupling 192 (Fig. 1) which, in turn, is pivotally connected for horizontal swinging movements by means of a pin 20 to an attachment 21 secured to the door, in spaced relation with the attachment 21. a

With respect to the door 10 adjacent to a side wall, as 14, the block 23 is connected by means of a horizontally disposed swivel pin 7 24 with a carriage or trolley 27 mounted to move to and fro in a horizontal track 25 of known construction, preferably of the U- type, which is secured to the wall as by means of brackets26.

The block 23 for the companion door 11 has its trolley track 25 supported by means of brackets 26 secured to the wall 13, such supporting frame.

track being disposed in offset angular relation to the wall substantially as represented in Figs. 2 and 6, so that the plane of the braces or rods, as indicated by 18 inFig. 2, will occupy an angular relation with respect to the wall 13 when the referred to door occupies the closed position in which it is represented by full lines in Figs. 1 and 2.

In its illustrated embodiment. the swivel pin 24 depends from the associated trolley (not shown) through a slot 252 (Fig. 6) in the bottom of the track 25 Each door is swung to open and close the same by means, of a cable 28 wound intermediate its length about a drum 29 (Fig. which is fixedly secured to a spindle S0 rotatable in a frame 31 which is secured to the: building wall, 13 or 1 1, remote from the respective door. 'A drum is actuated to. operate the associated door through: the. medium of acrank handle 32. fitting a, polygonal end of the spindle.

Said cable, one for the trolley of each door, has. its ends. 28 connected tothe as sociated trolley asby means, of a collar 33 mountedupon the respective swivel pin 24;,

. or 243-- and having vaperturcd lugs to. which said cable endsgaresecured, I

From said trolleyconnections, the cable passes about. guide pulleys, as 3. L and 3.5, and

thence to the drum. 29. I 1

For securing a. door in an adjusted position, I provide upon a drum spindle 30 a toothed wheel 36,. Fig; 5,. which. isadapted to beengaged by .a-detent. 37 controlled by glfinger 38 slid-able in .a slot. 39. oftheframe 0pemtion.A door is. swung about its hinges by means oft-he. respective. cable 28 actuated by a proper-turning of its-- drum 29 tocause. the trolley for the. door to be I moved in one direction or the otheru-pon the track therefor;

.Movement of the trolley ineitherdirection is transmitted to, the doorthrough.themedium ofthe stiff rod members 18., 19. ofthe door Such frame members moreover by being connected. inspaced apart relation. to the free side of adoor constitute two sides of a triangle which obviously pre-- vents any sag to the door.

Two-part doors are movable as a single piece when the parts thereof are. coupled together by thereleasable means 1'1.
